f1 '0 all whomit may concern. v v

Be it known that I, Gnonen lbrlllloons a citizen of the United States, residing at New York, inthe county of New York and ffltate of New York, have invented certain bustible" gas with decreased expense and with ncreased lntensity.

Anotherobject ofthe invention isto provide a device of this character which is compact,- easily installed, and wherein the liquid hydro-carbon and water are 'commingled in the proper proportions and Another object ofthe invention is to. provide a device-of this character in which the hydro-carbon and water elements are va- 'porized by the action of a preliminary heater or burner and thus preheated before passingto the main burner.

Anotherobject of the invention is to provioe a device of this character wherein a minor portion of the gas generated is utilized to generate an increased supply of gas leaving the major portion of the gas available for heating.

Another object of the inventionis to pro- ,vide a device of this character so arranged thatthe heated air is uniformly diffused and distributed uniformly in all directions. 7 Another object of the inventionis to'provide a device of this character including a gas generator, a preliminary burner and a main burner with nieans whereby a minor quantity of the gas is utilized to supply the preliminary burner and to heat the air and cause it to circulate over the main burner, thus leaving the major portion of the gas availablefor use in the main burner.

Another object of the invention is to pro vide a device of this character which isself contained, furnishes its own heated air and thereby materially increases theeiiiciency of the combustion. v a i Another object of the invention is to provide a device of this character wherein the heat radiated from the generating chamber trating the construction of the and; rising from a preliminary burner is utll zedto impart preliminary heat to the air pass ng to a main burner.

With these and other objects in viewj the invention consists in certain novel features ofconstruct on as hereinafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative of thepreferred embodiment of the inventi0n;

Fig. 9 is an enlarged sectionaldetail of the check valve between the vaporizing chamber and the main burner. The improved apparatus comprises a base member 10 upon which a lower shell member 11 is mounted and provided with a plurality of air apertures 12.

The lower shell member ll is provided with one or more side openings covered by swinging doors 13 of suitable construction to provide access to the interior ofthe lower Shelly .7 a

The lower shell 11 is also provided with an encompassing ring 14 to form a support for an upper shell comprising a cylindrical side wall 15, upper end 16 and lower end 17, the three members 15 16 and 17 being united gas tight, and constituting a generating chamber. a r a The end members l6 and llof the upper shell are each formed with a relatively large central opening surrounded by v at-- taching flanges to support atubular memberl8. 3 e 1' Connected at 19 to thelower end member 17 is a cylindrical support 20 depending below the ends 17 and providedjwith an internally threaded opening to support the lower threaded end of a conductor tube 21 of dust, insects or the like.

A. bell shaped tubular member having a supporting flange 26 is disposed upon the top member 16 of the outer shelland constitutes a continuation of the tubular memher or air duct 18, the flare or curvature of the member 25 corresponding to'and spaced from the flared end of theportion '22 of the member 21, as shown in Figs. 2

and 7.

Supported within the lower shell '11 is an annular gas burner 27 of approved construction, preferably supported by standards 28 from the bottom of the lower shell, and

provided with a plurality of orificeswhich form gas jets as shown.

The intake 29 for the lower burner is of the usual form, and leading into the intake is a feed pipe '30, the latter extending into the upper shell or generator "and upturned at the inner end as shown at 31. a

The pipe 30 is supplied with a controlling valveBQ, and operates to supply gas from the shell 15 to the burner 27.- 7

Supported preferably by standards 33 above the end 16 of the upper shell or generator and surrounding the flaring portions 22 and 25, is a larger and upper annular burner 3e. I

A conventional intake 35 leads into the upper burner 3d, and leading into the intake 35 is a feed pipe 36, the latter extending into the upper shell and terminating in an in wardly opening check valve 37 of approved construction.

A pilot burner 38 of approved construction is connected through the top 16 of the upper shell and terminates in a discharge nozzle or tip 39.

The upper shell delincd by the members l5, l6 and 1'7, as before stated, constitutes the generating chamber and is supplied with liquid hydro-carbon through feed pipe all) and water through pipe 42, the pipes being provided with suitable thermostatic control devices represented conventionally at 4:3 and 44.

With an apparatus thus constructed the operation is as follows:

The liquid fuel is fed into the upper shell or generator through the feed pipe 41 under the control of the thermostat device 43, and the water through the feed pipe e2, the lat ter having a controlling valve 45. By this means the feed to the upper shell or gener principle of the invention or sacrificing anv atoi' is cl'l'ectually controlled and caijiable of being supplied at a predetermined rate, and when the commingled elements come in contact with the bottom 1'? of the generator which is highly heated by the lower burner 27, they are volatilized and thus converted into ahighly inflammable gas. it relatively L small portion of this gas passes through the pipe 30 to the lower burner and thereby supplies the latter, while the may or portion of the gas passes to the upper burner by the feed me 36 d1s lacin the check valve 37 I r 7 b 1n 1ts passage. I I

The 'as enerated in the newer chamber or generater thus passesto three localities in the apparatus, the lower burner the pilot burner, and the main or upper burner.

The asses dlrectl to the lower burner a P J e. and the pilot burner, while the gas that passes to the upper burner is only the amount in excess of the requirements of the lower and the pilot burners, being held back by the check valve- 37.

Thethermostatic control ofthe liquid fuel and water is set at the minimum to insure the requisite burning of the lower and pilot burners, the check valve insuring the proper supply to the lower and pilot burners before any of the gas can reach the main burner.

The cool air enters through the intake lines 23 and passes thence through the space between the tubular members 18 and 21, and thence between the flaring portions 2:2 and 25, thus insuring the complete combustion of all of the gases by a constant supply of highly heated fresh air directly over the flames of the main or upper burner 34.

The inner tube 21 likewise possesses the two fold function as a means incfoact-ion with the tube 1.8 for conducting the heated air-to the upper burner, but also as a conductor for any fumes which may rise from the lower burner.

The improved device is simple in construction can be inexpensively manufactured, and of any required size or capacity, and may be installed in any locality where highly heated air is required. 1 I

The preferred en'ibodimcnt of the in vention is disclosed in the drawings and set forth in the specilicatioi'i. but it will he understood that modifications within the swipe of the claimed invention may be made in the constriiiction without dopafling from the of its advantages. i

Having thus'described the invention, what is claime as new is:

In an apparatus ofthe class described, agenerating chamber, a conductor for outside air formed of an outer and an inner flue extending through said generating chamber with their outlet ends flaring outwardly, a preliminary burner beneath said generating chamber in position to receive the air di charged thereover from the flaring outlet of t the air conductor fines, means for supplying hydro-carbon fuel to said generating chamber, means for supplying gas from said generating chamber to said preliminary burner, and means for supplying gas from said generating chamber to said main burner.

52.
